Cowboys come to terms with top draft pick Tyron Smith

The Cowboys and rookie right tackle Tyron Smith came to terms on a four-year deal with $12.5 million.

The unique thing about the contract for the first round pick out of USC is the entire deal is fully guaranteed.

It's another step for the Cowboys in shoring up their offensive line. They signed left tackle Doug Free to a four-year, $32 million contract on Tuesday and guard Kyle Kosier to a three-year, $9 million deal on Wednesday.

The Cowboys now must decide what to do with Marc Colombo who had been negotiating a pay cut to stay with the team but so far has yet to come to terms. He could be released today.
